C Lens
C-lens are specifically designed for fiber optics applications such as collimator, isolator, switch, collimator array and laser assembly. Compare to other gradient index lens, C-lens have several advantages including low cost, low insertion loss in long working distance, and wide working distance range.
Applications:
- Collimator
- Isolator
- Switch
- Laser Assembly
